CAN OPENER.

Application filed June 21, 1927.

This invention relates to can openers, and is more particularly directed to a can opener for use in removing the covers from cans including a body and a cover, which cover fits over the body of the can and engages an annular flange formed on the body of the can. which type of cans are commonly employed for the packing of shoe polish, baking pow der, and the like.

Many devices have been provided for opening cans, such as shoe polish cans, for example, key type openers including an cccentric disc secured to the body of the can in position to engage the downwardly extending flange of the cover of the can to force the cover from the body. This type of openers is expensive and must he furnished by the manufacturer of the can, thereby raising the cost of the can to the packer of the polish. Other forms of shoe polish cans are provided which are of the same type but'provide no means by which the cover may be removed so that it is necessary to insert a knife or sharp instrument under the downwardly extending flange of the cover in order to remove the cover.

In order to maintain the shoe polish in the proper condition, it is necessary after each use of the polish that the cover be replaced, thereby necessitating the removal of the cover each time it is desired to use the polish. It is, therefore, an object of this invention to provide an opener for cans including a body and a cover having a down Wardly extending flange which telescopes over a portion of the body and which open er will permit the cover to be 'eplaced on the body of the can so as to cover the polish therein and will also be easily operated to remove the cover.

Another object of this invention is to provide an opener for cans including ,a clamp ring, a ring mo "ably secured to the clamp ring, and means secured to the clamp ring for moving the movable ring axially relative to the clamp ring.

Other objects and advantages of this invention, it is believed, will be apparent from the following detailed description of apreferred embodiment thereof, as illustrated in the accompanying drawings.

In the drawings:

Figure 1 is a top plan View of a can opener embodying this invention.

Figure 2 is an edge elevation thereof.

Figure 3 is a fragmental sectional View Serial No. 200,351.

taken substantially on the line 33 of Figure 1.

in the preferred embodiment of this invention, illustrated in the accompanying drawings, 1 illustrates the body of a can having an annular outwardly extending flange 2. A cover 3 is provided for the body 1 of the can at the downwardly extending circumferential flange a to engage the outwardly extending annular flange 2. The cover 3 tightly fits the body 1 of the can to provide a substantially air-tight connection between the cover 3 and body 1 of the can.

A clamp ring 5 is provided which is constructed as a split ring and provided with means such, for example, as a thumb screw 6, for contracting the split ring in order to clamp the same to the cover 3. The thumb screw 6 passes through a bore formed in one ear 7 of the split ring and is screw-threaded in the other car 8 of the split ring. Interposed between the clamp ring 5 and the flange 2 of the body 1 are means for moving the body 1 of the can away from the clamp ring 5 so as to move the body of the can out of the cover 3. I prefer to interpose between the ring 5 and the flange 2 a movable ring 9 so that the ring 9 will engage the annular flange 2 at substantially all points. The ring 9 will be of a diameter greater than the cover 3 of the can and is slidably secured to the clamp ring in any suitable or desirable manner such, for example, as by means of a pair of pins 10 which are provided with heads 11 and pass through bores 12 formed in the clamp ring 5 and are screw-threaded into the movable ring 9, as illustrated at 13.

In order to move the movable ring 9 from the clamp ring 5 axially relative to the clamp ring 5, any suitable or desirable means may be provided. However, I prefer to employ a pair of thumb screws 14 for this purpose, which are screw-threaded through the clamp ring 5. as illustrated at 15, so as to engage at their bottom ends 16 the upper surface of the movable ring 9, in such a manner that as the thumb screws 14: are threaded through the clamp ring 5, they force the movable ring 9 away from the clamp ring 5 and hence against the annular flange 2 of the can forcing the can body 1 out of the cover 3.

. After the cover 3 has been removed from the body 1, the same is carried by the clamp ring so that the assembly of the clamp ring and cover may be replaced upon the body 1 of the can so as to maintain the can closed when not in use. Any other suitable or desirable form of means may be employed for forcing the integral ring 9 axially of the clamp ring 5 such, for example, as providing in the clamp ring 5 a recess 17 into which a screw driver'or the like may be inserted so as, to pry the movable ring away from the clamp ring 5 and hence pry the body 1 of the can away from the cover 3.

Having fully described my invention, it is to be understood that I do not wish to be limited to the details herein set forth which may obviously be varied without departing from the spirit of my invent-ion as defined by the appended claims.

I claim:

1. In a device 01": the class described, the combination of a clamp ring, a ring movably secured to the clamp ring,-and means for moving the said latter ring from the clamp ring.

2. In an opener for shoe polish cans having a substantially cylindrical body formed with an annular flange, and a cover adapted to fit over the upper portion of the cylindrical can and engage the annular flange of a clamp ring adapted to be clamped on the cover, a ring movably secured to the cover intermediate the clamp ring and annular flange, and means for moving the movable ring from the clamp ring to cause the same to engage the annular flange and force the cover oti' the body.

3. In a device of the class described, the combination of a clamp ring, means for locking the clamp ring a slidable ring, means for slidably securing the latter ring to the clamp ring to permitthe slidable ring to move axially relative to the clamp ring, and a thumb screw screw-threaded through the clamp ring to engage the slidable ring.

l. In a device of the class described, the combination of a clamp ring, a second ring, means secured to the second ring and slid ably engaged with the clamp ringto permit the second ring to move axially relative to the clamp ring, and means for moving the second ring from the clamp ring.
